Patent number: 10646326Abstract: The present disclosure relates, in some aspects, to orthopaedic implants for securing soft tissue to bone and methods for using the same. One particular implant comprises a first exposed porous surface region, having pores for promoting bone ingrowth, and a second exposed porous surface, having pores for promoting soft tissue ingrowth. At least some of the pores of the first exposed porous surface region may be seeded with osteocytic factors and at least some of the pores of the second exposed porous surface region may be seeded with fibrocytic factors. Such orthopaedic implants can advantageously facilitate regeneration of the soft tissue to bone interface.Type: GrantFiled: September 20, 2017Date of Patent: May 12, 2020Assignee: Zimmer, Inc.Inventors: Tao Jiang, Jian Q.

Patent number: 9579141Abstract: An orthopedic device holder and related system and method are disclosed. The orthopedic device holder can include a body member, a cannulated plunger, and a resilient member. The body member can include a longitudinal main body and an extension portion. The cannulated plunger can be slidably mounted inside the body member and movable between a first position and a second position. The plunger can be configured such that in the second position, a plunger distal end extends past a main body distal end, and in the first position, the plunger distal end assumes a more proximal position. The resilient member can be positioned adjacent a plunger proximal end and can be configured to urge the plunger towards the second position. The extension portion of the body member can project distally from the main body distal end and can include a locking member, which can be configured to fit into a mating recess of an orthopedic device.Type: GrantFiled: February 7, 2014Date of Patent: February 28, 2017Assignee: Zimmer, Inc.Inventors: John Chernosky, Ray Zubok, Timothy A.

Patent number: 9517138Abstract: A tibial support structure includes a platform portion and a medullary portion that are monolithically formed as a single piece. The medullary and platform portions of the augment component are adapted to accommodate and mechanically attach to a tibial baseplate, and are individually shaped and sized to replace damaged bone stock both within the tibia, as well at the tibial proximal surface. The monolithic formation of the tibial support structure provides a strong and stable foundation for a tibial baseplate and facilitates restoration of the anatomic joint line, even where substantial resections of the proximal tibia have been made. The tibial support structure may be made of a bone-ingrowth material which facilitates preservation and rebuilding of the proximal tibia after implantation, while also preserving the restored joint line by allowing revision surgeries to be performed without removal of the tibial support structure.Type: GrantFiled: November 21, 2014Date of Patent: December 13, 2016Assignee: Zimmer, Inc.Inventors: Ray Zubok, Jorge Montoya, Timothy A. Hoeman, John Chernosky, Keith A. Roby
